264 Win Mag Loads??? - 24hourcampfire

What is your favorite load for this caliber?

125gr partitions pushed by 7828.

let me ask this another way....

I am looking for loads for 139 scenars to work in my cooper 264 win mag.

Any help would be appreciated.

what powder range? manual shows 65-69 for 129 ab LR. Do you use that range for the 130s?

66 1/2 grs,cci mag primers

Great bullet.

I don't have a .264, but several other 6.5's.

RL-33 seems to be a favorite with some LR .264 shooters.

Send rcamuglia a PM. He has a lot of .264 experience.

I have some of the 139 scenars loaded up with US869 (working up to 77.o gr) that I need to get to the range with. I was able to get 3,150 with RL-33 and 140 NABs. The 139 Scenar has a very short bearing surface.

Sierra 100gr HP was my go to for deer. But I do like the 140gr Partition 130gr JLK VKD and Woodleigh 160gr PPSN.

68 grains of Retumbo worked well with 140's in mine. That's max and you need to work up to it.

The 139 Scenar is a super bullet. Shoots like a 140 Berger VLD, but is tougher.

IIRC, Rick (rcamuglia) tried WC-872 and I think US-869. He settled on RL-33 as the best .264 WM powder and he's burned a bunch of .264 powder. As you remember, RL-33 is similar to RL-17, made by the same Swiss company. It reportedly has a smooth pressure curve like RL-17.

Me, that's where I'd start with the .264 WM. With the 26 Nos, it's the other way around, 869/872 out perform RL-33.

Yep.

I've found RL-33 to be the best powder in the .264 for velocity. I'm shooting the 139 Scenar at WARP SPEED

3400 seems to work well in Balistic AE for correct drops as far out as my scope will travel (1250 yards)

Accuracy seems pretty fair too

Hundred grainers in the 6.5 RUMLN?

You'd vaporize those poor bunnies. It'd be like a great big .220 Swift on steroids...

No telling how good that gun will shoot when you get the bugs worked out...

Whats the barrel length on your rifle to get that speed????? W

120 e tip at 3400 with Magpro

Anyone use the scenar on game?

120 E-Tips perform great in the 26 Nos. My gun will go almost 1/2 MOA at 400 yds. (2 1/2"-3"). And with a 200 yd. zero, not that many clicks to be dead on at 400.

With 91 gr. 869, we're clocking around 3,450 fps. with 26" barrel, not leaning on it or pushing the pressure.

Double Tap ammo advertises their 26 Nos ammo with the 127 LRX at 3,600 fps. At almost a hundred bucks a box, I'll stick to handloading. Not sure how they're doing that, but would assume it's within SAAMI pressure limits.

how many grains?

68 gr Ramshot magnum, 120 gr ttsx, might get a itch to try RL 33 but I don't think it will deliver much more speed.

With the 100gr I use 72gr of H4831 The Sierra 100gr hp is 3691fps and the 100gr ballistic tip is 3709fps They hit hard and get there fast. Sierra takes 0.086 seconds to 100 yard target and still 3279fps and 2387ft lbs of energy, While the Nosler bullet is at 3382fps and 2540 ft lbs of energy and drops a hundredth of a second at 100yards. But then I step into the danger zone with the 160gr Woodleigh bullet at 3261fps. traveling 100 yards in 0.095 seconds and still at 3067fps and 3341ft lbs of energy. This is my Moose load.

70.1 grains of Ramshot Magnum gives a Barnes 127 LRX 3299 out of my EW model 70.

The 130gr JLK VDL is 3226 fps with 73gr H570 zeroed at 300 yards mid range is 3.5 inches high and it is traveling at 2767fps with 2209 ft lbs of energy and takes 0.301 seconds to get there. I have not been able to find the RL33 powder to try yet no one in my area carries it.

264wm,

Thanks for the info. I tried H4831 in my 6.5SLR today. I settled on 71.0 grains. Twice the velocity showed 3,750 fps with the GSCustom 106HV using Fed 215 Magnum primers. I guess the BC is about .485, but don't know exactly. Anyway this wildcat sure is close to the .264 Magnum in capacity.

Sounds like a keeper. Keep the info coming and are you getting good groups with it? That sounds like a interesting bullet I had not heard of it. I have pushed the 85gr Sierra HP to 3830fps and it is accurate at that speed. That was with 73gr H4831. Also the 95gr Vmax with 72gr H4831 is at 3691fps I am thinking I can get to 73gr with it which should bump it up.

Powder Valley has RL-33 in stock.

264wm,

I loaded ten cartridges this evening and will try to get to the range Thursday or Friday morning. I plan to fire them at 300 yards. If they group under 3", I will call it good and start practicing prone with a bipod and twisting the turret.

Range results from yesterday - first sunny day in eons, so I took the afternoon off and practically had the range to myself. Trying to stay on post in regards to the 139 scenar that the OP asked about.

Round robin (4 shot groups, 2 shot salvos, alternating bullets each time, 200 yds) accuracy trail w/ US869 and a few 139/140 bullets. Squirrely/gusty winds noted. T = 48F. All Fed 215 and Norma 7mm reformed, neck sized, 75.o gr US869. 1:9" twist, 25" bbl

139 Scenar (SD @ -0.030") v = 3,005 fps / group = 1.45"
140 NAB (SD @ -0.020") v = 3,020 fps / group = 2.55"
140 A-Max (SD @ -0.055") v = 3,010 fps / group = 5"

The 139 scenar smoked the other two.

Worked up to 77.o gr for 3,095 fps for pressure, but not groups. Need to start hoarding those scenars.

Next step would be to try some RL-33 and Retumbo with the Scenars.

I talked to a technician at Alliant yesterday and he told me that Rl 33 is made for large cases like the 300 ultra mag and 338 Lapua, he further stated that using it in the 264 is like playing with fire. He also stated that he heard of some actions getting stretched and guns being damaged by using RL 33 in a cartridge that it was not intended for, I think I am going to stick with Ramshot magnum and H 4831.

65g 7828 works with most 140's in mine. Usually clock around 3200 fps.

Why?

He did not say why but I am assuming that because RL 33 was developed for large capacity cases and Alliant did not do any testing in the 264 mag. If you want to use it in your 264 mag please do so and if it works well you might want to tell them, as for me I own a very nice pre 64 m70 264 and I plan on keeping it in one piece, is it worth that extra hundred feet per second to take a chance and ruin a good rifle and maybe hurt yourself, I think not.

Those company types will often stick to the script and only talk about loads they've tested. To say that RL-33 is "playing with fire" in rounds other than what they have data for sounds more like something you'd hear from one of those behind the counter gunshop Ninjas who seem to know everything.

Serious .264 WM LR shooters have done some great stuff with RL-33, some saying it's the best powder for that round, period.

Check post here on the Fire for data and performance reports.

Freddy, thanks for the info, but I'm not sure what it means for an action to get stretched.

IMO, an overzealous tech trying to scare the unwashed masses from veering too off the reservation.

The whole line of reasoning isn't reasonable.

DF

DF, so what you are saying is that if there is no data for a particular cartridge with a certain powder then we should go out and experiment on our own. I guess I can go out and load my 264 with RL 17 and see what happens.

Loonies work up loads every day, sometimes off the grid...

But, you gotta use common sense. If some are reporting very good results with RL-33 in the .264 (which they are), getting great accuracy, impressive speed without problems, that may be a place to start, dropping back and working up, of course. And it helps if the sources of that info are from respected shooters.

And no. I wouldn't fill a magnum case with a fast powder and see what it would do...

My Mamma didn't raise a fool...

Common sense, data from others and careful trial and error, using a chrono. I prefer company data with pressure testing but it's not always available.

Right now, I'm working with WC-872 in the 26 Nos. Although there's no factory data available, I know 872 is pretty close to 869 (so far about the best powder for that round) and loads are fairly interchangeable. I have compared notes with those who have used it. I have cases loaded with progressive charges and will seat bullets at the range. I'll be reading the chrono and watching groups. I hope to be impressed...

May even learn something...

The new Barnes 120 gr. TAC-X worked great today in my 26 Nos. I shot 400 yd. groups, a hair over 2".

I finally got some Nosler 129 ABLR's, but the 120 TAC-X out shot them. The 127 LRX was runner up at around 3".

You .264 guys may want to try the TAC-X.

Do you always act that way toward those who question you. All I did was post what a tech that works for a powder manufacturer told me, it seems you guys that are going off on your own get offended when someone questions you.

Chill Freddy, and laugh a little....you may live longer.

Offended is not the correct word. Entertained is a much better word. Also amused comes to mind. How do you think wildcatters get their load data?

"How do you think wildcatters get their load data?"

On the phone, talking to powder company techs...

DF

Must have struck a nerve with you 264 experts, really don't need your flack, went out this morning with a legitimate load of 62 gr H 4831, Nosler 120 gr BT. Shot a group that measured 1.5 in at 200 yards, shot a group at 300 that measured 2.9 inches, plenty good enough for me. If I need advice I will go to Shooters forum, less sensitive people there.

Thanks for telling us about h4831. I used that with 106 HV to average 3,754 for ten shots. I will use it to dial in the load with the adjustable brake.

I don't own a .264, although I've work with them.

Gotta have a tough skin here on the Fire...

And, it's all in fun, nothing personal...

DF

You are right about the tough skin, I was not trying to undermine anyone, just repeating what the tech told me. When I shot those loads I was attempting to zero a new scope. I replaced my old 6x Redfield with a Vortex Diamondback 4x12 with the dead hold recticle, with a dead zero set to 200 yards the first hash mark under the crosshairs should put me dead on at 300 but I am about inch and a half high at 300, I guess their calculations are based on a different bullet and velocity.

I love it here, learning from those who've done stuff I'll never do, helping others with problems I've faced.

The Fire experience is not all peaches and cream, trolls do exist, some contributors can get a bit crude, but the overall experience is worth the B.S., IMO.

Methinks there IS some here a little sensitive, and his name is Freddy.

Just relax and enjoy the banter...it's jut an Internet forum, not life & death.

Another thing to consider half these guys might be the same guy with a different name. I'm convinced you and I are different guys, but I don't know if you are one of the regular posters here who gives me a hard time in the optics forum.

Now, Ringman.

Those Optic Forum guys love you...

Velocity?

Looking at Loaddata.com, that load should run around 3,200 fps.

I've read that the 120 NBT is tougher than older BT's, which had a less that stellar reputation for holding together on game, particularly when driven fast.

BT's are known for accuracy.

Question: Is this a good bullet choice for WT's, etc. at 3,200 fps.?

I'm asking, because I really don't know.

DF

Based on Hodgdon reloading data a quick calculation puts Freddy at about 3110fps. But then I don't know what the bullet is traveling at. (LOL) If he loaded at max 64.6gr it would be 3254fps.

What's the consensus, 120 gr. NBT at 3,150-3,200 fps on WT's?

120's at 3,450+, I'm mono-metal all the way.

DF

But then 67gr of H4831 drives a 130gr JLK at 3249fps with no signs of pressure. but use caution I worked up to it.

Mine flings 120 TTSX's at 3,350. I want to say Retumbo.

I am pretty much mirroring this with my M70/26" Pac Nor. Dancing around 3350-3400 with 69.0gr RS Magnum which is about a max load according to Ramshot's online data. Currently shooting 0.030" off the lands and seeing 1.5" at 200yds. Nothing real in-depth on the load development, just something I threw together right before season opener last year. Going to play with seating depth a little and see what happens this summer...just for schits and giggles.

You may want to try even more jump, say .05" or even more.

DF

Yep, planned to move back in 0.010-015" increments and see what happened.

If I had to guess, based on my experience, you're gonna like big jump better than little jump...

But, I await your report.

That's how we learn.

DF

I am not the guy who is giving you a bad time about optics, Is he a Leopold kind of guy, I am a Burris and recently become a Vortex fan, I don't think there is a better scope in it's price range.

These are the old bt's, they came in a red box that says Solid base ballistic tip, they come in 100 to a box. I have about ten left, when I get a chance I will run them through the chrony. I bought them to use in my 6.5 Jap, this is the first time I shot them in my 264, I just tried them see how my new scope works, did not want to use my supply of Partitions and ttsx, I hope they are as accurate as the Noslers.

Those bullets are so old they might have mold. I used those to in .224 diameter to kill a doe and a buck a few years ago.

I shoot NBT out of a 300 WM. 165's with 79 Gr of RL 22. Chronos at 3230. That being said I shot a mule deer at 500 yards with this load. Broke the front shoulder - bullet exploded and had to put rohnd #2 in the ribcage to anchor him down. I have switched to AB's which believe it or not chrono at 100 fps slower even though they have the same BC...

Shot a 240 lb whitetail with my 264 win mag and a 130 accubond and the bullet hit the shoulder and bounced back creating a massive wound and ran down the hide. Found it intact and weighing 90 gr at his back knee - Guess im saying from my experience that the AB holds together better than the NBT....

No.

Realize that barrels and chambers differ.

A barrel with tighter tolerances in groove/land diameter will behave differently than others that may be more generous. Number of lands and gloves will also effect when you may find pressure.

Chambers with generous throats will behave differently than chambers that are short-throated. Etc...

With the same lot of powder in my old barrel that was worn, I was shooting 77 grains of RL-33 and the 140 VLD. Bullet bearing surface has an affect too.

My new barrel topped out at 72.5 grains at winter hunting temperatures (40°)

I'm shooting 72 grains and I have no problems. RL 33 is definitely temperature sensitive and I won't be shooting it at 80°+

No.

Realize that barrels and chambers differ.

A barrel with tighter tolerances in groove/land diameter will behave differently than others that may be more generous. Number of lands and gloves will also effect when you may find pressure.

Chambers with generous throats will behave differently than chambers that are short-throated. Etc...

This is the reason I hang out here. Great information. Thank you.

Crank: have you had any experience with how the 140 Sierra reacts when it contacts fur?

I worked up the load for the boattail bullet. I have not shot an animal as of yet with the load or bullet. Will post my resluts from my efforts in this forum (hopefully) later this year.

Do you have any expierence on game with this bullet?

Also worked up another load:

66 GR of RL 22
Fed 215 Primer
Win Brass
Seat 20 thousandths off of the Lands
26" pre 64 model 70
pushing 3290 FPS

I do not. It's quite accurate. But I'm a little leery of Sierra GK's when pushed too fast.

I can guarantee that I will test this on a big fat doe before I shoot at good buck with it!

I'll be waiting for your report

Will do.
